I don't want to know if you do it, find it beneficial etc. I want to know if anyone has ever seen studies that point to chronic muscle fatigue vs exercise. My left leg in particular fluctuates between almost normal to zero strenght. Its always worse during a relapse but it seems to never be really strong, always have tremors, only there, after standing for a few moments, buti t does make me question i f it is simply deconditioning(dr's viewpoint) since it isnt' at a constant state but depends on my general health. After PT sessions for right knee replacement, the quad exercises i did for both legs left the left completely weak, even after 12 weeks. It would recover but next session same thing and never got stronger permanently. So my question is, has anyone read anything if its possible to gain lasting, i repeat, lasting strength in muscles affected by ME/CFS? I also have had lower back disc problems. At the time that happened didn't have health insurance so the cursory at best care you get under those circumstances. I don't know if that could be impacting the problem. My dr wants me to do more PT but im not wasting the energy/potentially causing a flare for nothing.
